The clothes you sweat, stretch, and recover in should be the cleanest ones you own.

That's why every article we make is independently tested for BPA, PFAS, and 50+ chemicals and engineered with one of the lightest environmental footprints in activewear.

Precision-fit athletic wear engineered for lasting comfort, unrestricted movement, and real performance.

Sustainable Synthetics

Not all synthetics are created equal.

The case
Synthetic fabrics offer the best performance available — stretch, moisture management, durability. That was never the debate.
The problem
Traditional synthetic are often treated with chemicals like PFAS and BPA and shed microplastics that last for centuries. These toxic microplastics enter waterways, accumulate in ecosystems, and make their way into our food chain.
Our answer
Our performance fabrics are infused with CiCLO® — an OEKO-TEX® certified fiber technology designed to accelerate biodegradability - significantly reducing long-term microplastic pollution. Every finished garment also undergoes independent testing to verify it's free of BPA, PFAS and 50+ other harmful substances.
We're not claiming perfection. We are claiming the highest standard available today.

The Founder Story

Every Product Tested

Articles made to last, just not forever.

Thanks to CiCLO® technology, our performance fabric will biodegrade when discarded like wool or cotton - dramatically reducing long-term microplastic pollution. This is done without any impact to fabric performance.
Sustainabilty

We are planet lovers

Microplastics are tiny fibers that shed from performance fabrics when you wash and wear them. Microplastics are everywhere: oceans, drinking water, even inside our bodies.

That's why we use CiCLO - it helps our performance fabric break down like cotton or wool, naturally, when discarded. Still high-performance, just less permanent.

Sustainabilty
